构造了一种新型的朗缪尔槽，它利用大量的Peltier元件和一台微型计算机，根据程序精确地控制水面温度。在直线加热或直线冷却过程中，我们可以通过将槽薄到2 mm来抑制槽内的水对流。该槽非常适合测量难于精确测量的不溶单分子膜的A-T等压线和π-T等压线。在完全抑制对流的A-T等压线测量过程中，新研制的槽可以清晰地观察到不溶性单分子膜的布鲁斯特角显微镜(BAM)图像。
A new type of Langmuir trough was constructed in which temperature of the water surface is controlled precisely according to a program using a large number of Peltier elements and a microcomputer. We can suppress convection of the water in the trough during linear heating or linear cooling by planning the trough as thin as 2 mm. This trough is very suitable for measuring A-T isobars and π-T isochores of insoluble monolayers which are rarely measured precisely. The newly developed trough can permit observation of Brewster angle microscopic (BAM) images of insoluble monolayers clearly during measurements of A-T isobars by suppressing convection completely.
